Go Modules API

healthy 3,063 Subscribers

The Go package ecosystem as an API. Look up any Go module by its import path for its latest version, license, source repository, total version count and known security advisories; read a module's full version history with publication dates; and get a module's declared dependencies — direct and indirect — parsed straight from its go.mod, with the required Go version. Covers the entire public Go module graph, from github.com/gin-gonic/gin, github.com/spf13/cobra and golang.org/x/text to gorm.io/gorm and k8s.io/client-go. Live from the official Go module proxy (proxy.golang.org) and Google's deps.dev. Ideal for dependency and supply-chain tooling, SBOM generation, package dashboards and Go developer portals. Modules are addressed by full import path. Open data.

Terraform Registry API — oanor API marketplace

Terraform Registry API

The Terraform Registry — the home of Terraform and OpenTofu modules and providers — as an API. Look up any module for its latest version, total downloads, source repository, verified status, publish date and a ready-to-paste usage block, plus counts of its inputs, outputs and managed resources; read a module's full version history; search the registry of thousands of community modules (optionally filtered by provider); and look up any provider for its version, download count and tier (official / partner / community). Covers the infrastructure-as-code ecosystem from the terraform-aws-modules VPC, EKS and RDS modules to the hashicorp/aws, google and azurerm providers. Live from the official registry.terraform.io API. Ideal for IaC and GitOps tooling, module catalogs and dashboards, and platform-engineering automation. Open data from the Terraform Registry.

 Homebrew Install Analytics API — oanor API marketplace

Homebrew Install Analytics API

Live install analytics for Homebrew, the macOS and Linux package manager, from the public formulae.brew.sh feed — no key, nothing stored. The adoption view of the Homebrew ecosystem: how much each command-line formula and each desktop-app cask is installed, and the most-installed packages overall, distinct from the Homebrew formula-catalog API in the catalogue (which describes a package — this measures how much it is actually used). The formula endpoint returns a command-line tool's install counts over 30, 90 and 365 days plus install-on-request, with its version and description. The cask endpoint returns a desktop app's install counts. The top endpoint returns the most-installed formulae or casks over a chosen window, ranked. Build developer-tool popularity dashboards, "is this tool still maintained and used" widgets, package-trend trackers and ecosystem-health tools on top of real Homebrew analytics. Look up a formula by its name (wget, node, ffmpeg) or a cask by its token (google-chrome, visual-studio-code); counts come from Homebrew's opted-in user analytics.

 PyPI Download Stats API — oanor API marketplace

PyPI Download Stats API

Live PyPI (Python Package Index) download analytics from pypistats.org — no key, nothing stored. The adoption view of a Python package: how much it is downloaded, the daily trend, and the breakdown by Python version and operating system, distinct from the PyPI registry-metadata API in the catalogue (which describes a package — this measures how much the community actually uses it). The recent endpoint returns the headline download counts: last day, last week and last month. The overall endpoint returns the daily download timeline so you can chart growth. The python endpoint breaks downloads down by Python version, showing which versions the package's users are actually on. The system endpoint breaks downloads down by operating system — Linux, Windows and macOS. Build package-popularity dashboards, dependency-adoption trackers, "which Python version should we still support" tools and ecosystem-trend widgets on top of real PyPI download data. Look up any package by its PyPI name (requests, numpy, flask); names are normalised to lowercase and the version and system splits include each category's share of total downloads.

 AUR API — oanor API marketplace

AUR API

The Arch User Repository (AUR) as an API. Look up any AUR package for its version, description, upstream URL, maintainer and submitter, community votes and popularity score, license, out-of-date flag, keywords and full dependency lists (depends, make-depends, opt-depends), plus its source snapshot and ready-to-run git-clone command; search the whole AUR by name, description, maintainer, dependencies or keywords (results sorted by popularity); and list every package maintained by a given user. Covers the 90,000+ community-maintained packages of Arch Linux, from yay, paru and visual-studio-code-bin to google-chrome and spotify. Live from the official AUR RPC. Ideal for Arch/AUR helpers and dashboards, package and dependency tooling, and Linux developer portals. Open data from the Arch User Repository.
